4 Claims.

This invention relates to swinging windows and the object of theinvention is to provide a window in which the sash guides are hinged atthe top of the window frame and arranged to be swung inwardly with thesash therein to allow cleaning of the window from the inside of thebuilding.

Another object of the invention is to provide a swinging window in whichthe sash guides are hinged at the top of the window frame and arearranged to be swung inwardlyythe sash guides and weights being arrangedso that thesash may be withdrawn from the guideswhen the guides areswung inwardly and will automatically dis- 5 engage from the sash cordsas they are withdrawn from the sash guides.

Another objecto-f the invention is to provide an arrangement whereby thesash upon being re-inserted in the sash guides and moved upwardly willautomatically re-engage the sash cords so that thesash will becounterbalanced bythe sash weights. I

A further object of the invention is to provide a swinging windowarranged ,so that a storm '25 window or screen may be inserted in placein the window opening from the interior of the building.

These objects and the several novel features of the inventionarehereinafter more fully described and claimed and the preferred formof construction by Whichthese objectsare attained is shown theaccompanying drawings in which-- Fig. 1 is an elevation of a swingingwindow embodying my invention .as it appearsfrom the interior ofthefibuilding.

The window frame I shown in Fig. 1 is formed to provide a'frame aboutthe usual Window opens ing and is provided with a cross piece 2 acrossthe top of the window opening as shown in Fig. 8. The sash guides 3 and4 are connected at the top by a cross piece 5 which is hinged by meansof the hinges 6 to the-cross piece 2 at the top '5 of the window frame.This provides an inverted U-shaped frame in which the cross piece 5forms the connecting member. This U-shaped frame may be swung as a uniton the hinges 6 shown in Figs. 1 and 8. The sash guide 3 is formed 10 ofsheet metal and. is shown moreparticularly in Figs. 7 and 8 and thisguide is provided with a parting stop I and a trim stop 8 extendinglongitudinally thereof. The sash guide 4 is a duplicate of the sashguide 3 and it will be noted 15 that the inner edge 9 of each sash guideis out-turned toprovide a channel for the upper sash while the lowersash is positioned between the trim stop 8 and the parting stop I. Whenin positionfor use as shown in Fig. l, the sash guides 3 and 4 engagebehind latches III which hold the sash guides in place in the windowframe.

As will be understood from. Fig. 5 a bracket I I is attached to theupper corner on each side of the inverted U-shaped sash retaining memberand. each bracket II carries pulleys I2 for the sash cords I3 and also aroller I4 over which the cords extend. It will also be noted from Figs.2 and 5 that the window frame is cut out at 33 to allow the pulleys toturn with the inverted U-shaped sash retainer. The cord l3 extendsdownwardly and about a pulley I5 on a sliding sash weight I6 shown inFigs. 2 and 3 and this sash weight rides in guides I! provided thereforon the window frame. Each end of the sash cord is attached to a sashengaging latch l8 7 shown moreparticularly in Fig. 6 which isprovidedwith a flat spring IS on theside thereof and with a latch end 20 whichis triangular in 40 form. In the normal position shown in Fig. 5, thislatch end 20 engages beneath a shoulder 2I provided therefor in the sashand having .a pocket 22 into which the end 20 may be positioned. It isalso to be noted that the sash 45 guide 3 is provided with an aperture23 into which the latch end 20 may move when the parts are in theposition shown in Fig. 6. The cord I3 extends from the latch for thelower. sash over the pulleys I2 and I4 thence downwardly and about thepulley I5 andthence upwardly again .over the pulleys I2 and I4 anddownwardly tothe sash engaging latch for the upper sash. ,By thisarrangement, a single sash Weight is provided for'bothsash andas'thisconwindow the sash gmay Y anced.
